Abstract
Heraclitus (55 miles) is fairly well worn down with some parts of its rim reaching upwards to over 1½ miles. Its north rim is completely destroyed by Licetus and its southwestern rim is similar damaged by a 31 mile crater. Instead of a central peak, there is a central crest running northeast from the rim of intruding southern crater almost to the rim of Licetus. I would estimate its height at less than ½ mile. The floor is rough and my 6 inch refractor reveals several small craters on the eastern side of the central crest. Find this one 6 days after new Moon.
Licetus (45 miles) is a great circular crater, over 2 miles deep. There are two sizable craters that have destroyed part of its southern rim. The floor contains many small craters and a small central hill.
